Adsense CPC trickle down effect

Hello Forum,

So far I haven't cared about the CPC when writing my content. Now that my site is getting some traffic and see that my CPC is mostly between $0.01-0.20

To improve my earnings I want to target higher CPC keywords in future articles, but my KW search shows me that the traffic will be likely a lot less for those posts.

Will targeting higher CPC keywords also improve the ADs and CPC for the posts that get high traffic right now but low CPC as the profile for my website changes, or are the blog posts isolated in that sense and the posts with high traffic will remain with low CPC ADs?

The keywords are all under the same topic of course.

The question is.

Will it be worth to write high CPC posts that get little traffic to improve the CPC of the website as a whole?

Yup it worth it, Go for articles with medium keywords with high cpc rates. It also depend on overall traffic quality of your site.

Ok, so targeting keywords like "topic A - education/school/business etc." that often see a higher CPC might be worth even though the overall search volume is lower than other keywords.

Traffic Quality means: Origin Country, Age and Spending Power of my visitors?
